Hi everyone,
I'm building a matrix in R with a cycle for like this:
pp_ris2=matrix(NA,6,6)
for(i in 0:6){
for(j in 0:6){
if(i>j){
pp_ris2[i,j]=myfunction}
else if(i==j){
print(c(i,j))
pp_ris2[i,j]=myfunction}
}}
but the result is:
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 0.062 NaN NaN NaN NaN NaN
[2,] 0.083 0.022 NaN NaN NaN NaN
[3,] 0.072 0.022 0.004 NaN NaN NaN
[4,] 0.046 0.016 0.003 0.001 NaN NaN
[5,] 0.023 0.009 0.002 0.000 0 NaN
[6,] 0.010 0.004 0.001 0.000 0 0
my problem is in the first column and row because in this matrix there are
not the column and the row with i=0 and j=0. Can anyone help me please?
thanks a lot
